In the left panel go to My Account -> My Workers.
Create a worker with any name (like "Worker1") with any password (even "Worker1Password" is ok), the password is just formal, it has nothing to do with your account security.
Correct your command line to:
./cpuminer -a yescryptr16 -o stratum+tcp://cryply.luckypool.org:9996 -u YourAccountName.Worker1 -p Worker1Password
is it for me )))) ?

i can't login!!!!!! not create a woker ))))
